* Passive House buildings allow for space heating and cooling related energy savings of up to 90% compared with typical building stock and over 75% compared to average new builds. Passive House buildings use less than 1.5 l of oil or 1.5 m<​sup>​3</​sup>​ of gas to heat one square meter of living space for a year – substantially less than common “low-energy” buildings. Vast energy savings have been demonstrated in [[basics:​passive_houses_in_different_climates:​passive_houses_in_mediterranean_climate|warm climates]] where typical buildings also require active cooling. ​

* Passive House buildings make efficient use of the sun, internal heat sources and heat recovery, rendering conventional heating systems unnecessary throughout even the coldest of winters. [[basics:​summer|During warmer months]], Passive House buildings make use of passive cooling techniques such as strategic shading to keep them comfortably cool.

* Passive House buildings are praised for the high level of [[basics:​building_physics_-_basics:​thermal_comfort|comfort]] they offer. Internal surface temperatures vary little from indoor air temperatures,​ even in the face of extreme outdoor temperatures. Appropriate [[planning:​thermal_protection:​windows|windows]] and a [[planning:​thermal_protection:​integrated_thermal_protection|building envelope]] consisting of a highly insulated roof and floor slab as well as highly insulated exterior walls keep the desired warmth in the house – or undesirable heat out.
